 ## Description
-LatAnalyze is a C++11 library for statistical data analysis based on bootstrap
+LatAnalyze is a C++14 library for statistical data analysis based on bootstrap
 resampling. It has been written with lattice QCD data analysis in mind (hence
 the name), but its features are not lattice specific and can be used more general statistical context.
 
-Sadly a proper documentation was never written, but some comprehensive examples covering most features can be found in the `examples` directory.
+Sadly a proper documentation was never written, but some comprehensive examples covering several key features can be found in the `examples` directory.
 
 The main features are the following:
 
 * Array and matrix types with fast arithmetic operations based on [Eigen](http://eigen.tuxfamily.org).
 * High-level types for bootstrap sample manipulation (including various statistical estimators and histogramming).
 * Mathematical expression parser for runtime defined functions.

 * Non-linear regression with error on independent variables (through total least squares).
 * High-level wrappers to numerical integrator and non-linear solver from the [GSL](http://www.gnu.org/software/gsl/).
 * High-level functional types for function of model. General functions can be defined from C pointers, C++ objects, strings of mathematical expressions or tabulated data.

 ## Installation
 The head of the `master` branch always points to the latest stable release. The `develop` branch is the main unstable branch of LatAnalyze.
 
-LatAnalyze is written in C++11 and requires a rather recent C++ compiler to be built. It has been successfully built on various Linux and OS X platforms using clang (from 3.7), GCC (from 4.9) and the Intel C++ compiler (2016).

-Additionally, autoconf, automake (from 1.11), libtool, bison (from 3.0) and flex are necessary to build the library. Unless you use a very exotic system, these tools are standard on any Unix platform and should be already present or easy to install through a package manager.

-Below are instructions for a quick installation. For a more customised installation, one first needs to generate the build system by running `./bootstrap.sh` in the root directory. Then the library can be built and installed through the usual GNU mantra `./configure <options> && make && make install`. Use `./configure --help` to obtain a list of possible options for `./configure`. Because Eigen expressions rely a lot on inlining and compiler optimisations it is strongly recommended to set the `CXXFLAGS` variable to `-O3 -march=native -mtune=native`.

+## Using LatAnalyze in CMake projects
+When LatAnalyze is installed, the necessary CMake module configuration files to link against the library are available in the installation prefix.
+
+To link against LatAnalyze in a downstream CMake project, simply use
+```cmake
+find_package(LatAnalyze)
+target_link_libraries(<my_app> LatAnalyze::LatAnalyze)
+```
+where `<my_app>` is a CMake target. If LatAnalyze was installed in a non-standard prefix, you might have to set `CMAKE_PREFIX_PATH` accordingly for `find_package` to be successful.
+
+You can additionally modify the `find_package` to ensure specific components are supported
+```cmake
+find_package(LatAnalyze REQUIRED COMPONENTS <...>)
+```
+where `<...>` is a space separated list of components. Currently available components are
+- `MINUIT2`: Minuit 2 minimisers
+- `NLOPT`: NLopt minimisers
 
 ## History

-# SYNOPSIS
-#
-#   AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
-#
-# DESCRIPTION
-#
-#   Check for baseline language coverage in the compiler for the C++11
-#   standard; if necessary, add switches to CXXFLAGS to enable support.
-#
-#   The first argument, if specified, indicates whether you insist on an
-#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
-#   -std=c++11).  If neither is specified, you get whatever works, with
-#   preference for an extended mode.
-#
-#   The second argument, if specified 'mandatory' or if left unspecified,
-#   indicates that baseline C++11 support is required and that the macro
-#   should error out if no mode with that support is found.  If specified
-#   'optional', then configuration proceeds regardless, after defining
-#   HAVE_CXX11 if and only if a supporting mode is found.

-# SYNOPSIS
-#
-#   AX_LIB_HDF5([serial/parallel])
-#
-# DESCRIPTION
-#
-#   This macro provides tests of the availability of HDF5 library.
-#
-#   The optional macro argument should be either 'serial' or 'parallel'. The
-#   former only looks for serial HDF5 installations via h5cc. The latter
-#   only looks for parallel HDF5 installations via h5pcc. If the optional
-#   argument is omitted, serial installations will be preferred over
-#   parallel ones.
-#
-#   The macro adds a --with-hdf5 option accepting one of three values:
-#
-#     no   - do not check for the HDF5 library.
-#     yes  - do check for HDF5 library in standard locations.
-#     path - complete path to the HDF5 helper script h5cc or h5pcc.
-#
-#   If HDF5 is successfully found, this macro calls
-#
-#     AC_SUBST(HDF5_VERSION)
-#     AC_SUBST(HDF5_CC)
-#     AC_SUBST(HDF5_CFLAGS)
-#     AC_SUBST(HDF5_CPPFLAGS)
-#     AC_SUBST(HDF5_LDFLAGS)
-#     AC_SUBST(HDF5_LIBS)
-#     AC_SUBST(HDF5_FC)
-#     AC_SUBST(HDF5_FFLAGS)
-#     AC_SUBST(HDF5_FLIBS)
-#     AC_DEFINE(HAVE_HDF5)
-#
-#   and sets with_hdf5="yes".  Additionally, the macro sets
-#   with_hdf5_fortran="yes" if a matching Fortran wrapper script is found.
-#   Note that Autconf's Fortran support is not used to perform this check.
-#   H5CC and H5FC will contain the appropriate serial or parallel HDF5
-#   wrapper script locations.
-#
-#   If HDF5 is disabled or not found, this macros sets with_hdf5="no" and
-#   with_hdf5_fortran="no".
-#
-#   Your configuration script can test $with_hdf to take any further
-#   actions. HDF5_{C,CPP,LD}FLAGS may be used when building with C or C++.
-#   HDF5_F{FLAGS,LIBS} should be used when building Fortran applications.
-#
-#   To use the macro, one would code one of the following in "configure.ac"
-#   before AC_OUTPUT:
-#
-#     1) dnl Check for HDF5 support
-#        AX_LIB_HDF5()
-#
-#     2) dnl Check for serial HDF5 support
-#        AX_LIB_HDF5([serial])
-#
-#     3) dnl Check for parallel HDF5 support
-#        AX_LIB_HDF5([parallel])
-#
-#   One could test $with_hdf5 for the outcome or display it as follows
-#
-#     echo "HDF5 support:  $with_hdf5"
-#
-#   You could also for example, override the default CC in "configure.ac" to
-#   enforce compilation with the compiler that HDF5 uses:
-#
-#     AX_LIB_HDF5([parallel])
-#     if test "$with_hdf5" = "yes"; then
-#             CC="$HDF5_CC"
-#     else
-#             AC_MSG_ERROR([Unable to find HDF5, we need parallel HDF5.])
