Since our default compilers are not gcc (icc, pgcc, cc, xlc_r etc) we've introduced FLEXLM_C_COMPILER and friends to be able to compile this from a single source tree.
But perhaps it would be cleaner to off-load it with ExternalProject_Add(). Seriously, how often do you want to compile LAPACK, BLAS, MPI, FLEXlm yourself...
