## Linking to your program
The `make install` command takes care of installing the QMCkl shared library on the user machine.
Once installed, add `-lqmckl` to the list of compiler options.
In some cases (e.g. when using custom `prefix` during configuration), the QMCkl library might end up installed in a directory, which is absent in the default `$LIBRARY_PATH`.
In order to link the program against QMCkl, the search paths can be modified as follows:
`export LIBRARY_PATH=$LIBRARY_PATH:<path_to_qmckl>/lib`
(same holds for `$LD_LIBRARY_PATH`). The `<path_to_qmckl>` has to be replaced with the prefix used during the installation.
If your project relies on the CMake build system, feel free to use the
[FindQMCKL.cmake](https://github.com/TREX-CoE/qmckl/blob/master/cmake/FindQMCKL.cmake)
module to find and link the QMCkl library automatically.

#===========================================
# Try to find the QMCkl library;
# If found, it will define the following variables (note the plural form):
# QMCKL_FOUND - System has libqmckl;
# QMCKL_INCLUDE_DIRS - The QMCKL include directories;
# QMCKL_LIBRARIES - The libraries needed to use QMCKL;
# If QMCKL has been installed in a non-standard location, one can set an
# environment variable $QMCKL_DIR in the current shell:
# $ export QMCKL_DIR=<custom_path>
# to indicate the prefix used during the QMCKL installation
# (typically `./configure prefix=<custom_path> ..` or `cmake -DCMAKE_INSTALL_DIR=<custom_path> ..`)
# This file should be located WITHIN your project source tree.
# (e.g. in cmake/FindQMCKL.cmake)
# How to use it in your project CMakeLists.txt:
# This is needed to locate FindQMCKL.cmake file, modify it according to your source tree.
# list(APPEND CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake/")
# find_package(QMCKL)
