SYMBOLSUFFIX have no effect when building static library

[vryy]

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
.....

Yes, pre- and postfixing is only implemented for shared libraries, to prevent symbol clashes in environments like Python where packages might depend on different builds of openblas (a typical example for this being numpy and scipy that are often used together=
