CMakeDetermineCXXCompiler.cmake doesn't accept 'c++' as compiler name

The commit b12aec6c modify Modules/CMakeDetermineCXXCompiler.cmake file with following changes:

-    if (COMPILER_BASENAME MATCHES "^(.+-)(clan)?[gc]\\+\\+(-[0-9]+(\\.[0-9]+)*)?(-[^.]+)?(\\.exe)?$")
+    if (COMPILER_BASENAME MATCHES "^(.+-)?(clang\\+\\+|g\\+\\+|clang-cl)(-[0-9]+(\\.[0-9]+)*)?(-[^.]+)?(\\.exe)?$")

The old logic accept clang++ g++ c++ The new logic doesn't accept c++

It block our product, c++ should be add:

if (COMPILER_BASENAME MATCHES "^(.+-)?(clang\\+\\+|[gc]\\+\\+|clang-cl)(-[0-9]+(\\.[0-9]+)*)?(-[^.]+)?(\\.exe)?$")
