New detection flow:
1. check for IGC__IGC_TARGETS and respect if defined -> IGC available
2. on Linux try using pkg-config to find IGC
- package can be part of workspace, in this case we have to tweak
some variables
3. check whether igc folder contains CMakeLists.txt and do
add_subdirectory if yes.
4. IGC not available -> fail
other changes:
- rename compiler.config to match name from IGC devel package
