SYMBOLSUFFIX have no effect when building static library

It seems that SYMBOLSUFFIX only works with BUILD_SHARED_LIBS=ON, at least from what I understood from reading CMakeLists. To confirm this, I compiled openblas using the options below

%CMAKE_COMMAND% ^ -G "Ninja" ^ -D CMAKE_BUILD_TYPE:STRING="Release" ^ -D CMAKE_INSTALL_PREFIX="%LAPACK_DIR%" ^ -D CMAKE_C_COMPILER="cl.exe" ^ -D CMAKE_CXX_COMPILER="cl.exe" ^ -D CMAKE_Fortran_COMPILER="ifx.exe" ^ -D CMAKE_Fortran_FLAGS="" ^ -D SYMBOLSUFFIX="_" ^ -D CMAKE_VERBOSE_MAKEFILE:BOOL=OFF ^ -D BUILD_SHARED_LIBS:BOOL=OFF ^ -D BUILD_STATIC_LIBS:BOOL=ON ^ -D BUILD_WITHOUT_CBLAS:BOOL=ON ^ -D BUILD_WITHOUT_LAPACKE:BOOL=ON ^ -D BUILD_LAPACK_DEPRECATED:BOOL=ON ^ -D BUILD_TESTING:BOOL=OFF ^ %LAPACK_HOME%

And extracting the symbol:

dumpbin /SYMBOLS openblas.lib | findstr /i "dgemm" 02C 00000000 UNDEF notype External | dgemm .....
