# CONFIGURATION
#
# * Any variable/value that is CACHE-ed can be changed after the initial run of cmake
# through the file, CMakeCache.txt which is in the build directory.
# * If you change any value in CMakeCache.txt, then just run cmake ..
# and the changed will be picked up. One can also use -DVARIABLE=VALUE
# when calling cmake to changed configuration values.
# * CMAKE_C_COMPILER, CMAKE_CXX_COMPILER, CMAKE_ASM_MASM_COMPILER, CMAKE_ASM_COMPILER,
# CMAKE_Fortran_COMPILER can only by specified on the initial run of cmake.
# This means you cannot specify -DCMAKE_C_COMPILER= on a subsequent run of cmake
# in the same build directory until that build directory is emptied.
# If you want to change the compiler, then empty the build directory and rerun cmake.
