Fixing ICPC usage with modern cmake and wrappers 

Related to conan's conan-io/conan-center-index#25843

replaced 'fp-model strict' by 'fp-model=strict' https://www.intel.com/content/www/us/en/docs/cpp-compiler/developer-guide-reference/2021-8/fp-model-fp.html
for more compatibility with nvcc. as 'fp-model=strict' will be directly
transmited to the compiler while 'fp-model strict' will have 'strict'
being treated as a file input.

Also added a CXX only filter for newer cmake 3.3+
