# LibompExports.cmake
#   Copy library and header files into the exports/ subdirectory after library build

# Create the suffix for the export directory
# - Only add to suffix when not a default value
# - Example suffix: .deb.30.s1
#   final export directory: exports/lin_32e.deb.30.s1/lib
# - These suffixes imply the build is a Debug, OpenMP 3.0, Stats-Gathering version of the library
