In ROCm 4.5.0 hip compile flags are coming in differently. This has caused some parsing issues for the HIP_COMPILER_FLAGS variable. As an example ROCm 4.3.0: --offload-arch=gfx900 ROCm 4.5.0: <$<COMPILE_LANGUAGE:CXX>:SHELL:--offload-arch=gfx900> Using existing code... $<$<COMPILE_LANGUAGE:CXX>:SHELL:--offload-arch=gfx900> Becomes... $<$<COMPILE_LANGUAGE:CXX>:SHELL: There are two problems with that. 1) The "<" is not balanced with a "> due to the regex consuming the ">" 2) There is still a `SHELL:` label. This commit repairs both. I took the regex parsing code from ROCmSoftwarePlatform/MIOpen/blame/develop/CMakeLists.txt but improved it to support handling of target features like <$<COMPILE_LANGUAGE:CXX>:SHELL:--offload-arch=gfx900:xxx+> Co-authored-by:Paul Fultz II <pfultz2@yahoo.com> Co-authored-by:
