Subject: Fix regex on find clang without stripping defines content
With this regex the example test code of clang fails in cmake, causing an error.
this is due to -I/usr/lib/llvm-18/include -std=c++17 -fno-exceptions -funwind-tables -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS
becoming:
-I/usr/lib/llvm-18/include;-D_GNU_SOURCE;-D_FILE_OFFSET_BITS;-D_LARGEFILE_SOURCE;-D_FILE_OFFSET_BITS;-D__STDC_CONSTANT_MACROS;-D__STDC_FORMAT_MACROS;-D__STDC_LIMIT_MACROS
If you undefine _FILE_OFFSET_BITS and you enable _TIME_BITS=64 you get a FTBFS
/usr/include/features-time64.h:26:5: error: #error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"
26 | # error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"
