HAVE_OPENMP is not in CMakeCache.txt because you did not defined
it to be a cache var.
However, I don't think HAVE_OPENMP have to be a cache var for this to work.
We are missing your CONFIGURE_FILE statement how does it look like?
May be you can try a simple test:
set(OPENMP_FOUND 1)
if (OPENMP_FOUND)
SET (HAVE_OPENMP 1)
SET (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
endif()
configure_file(${CMAKE_CURRENT_SOURCE_DIR}/config.hpp.in
${CMAKE_CURRENT_BINARY_DIR}/config.hpp)
with your current config.hpp.in.
If this does not generate the appropriate config.hpp file then
send this minimal project (CMakeLists.txt + config.hpp.in) on the list.
Which version of CMake are you using?
What is your platform (Linux, Windows, MacOS...)
