Dear all,
I found the problem finally. What I did was mixing strings and lists (as I
understand it), so I set the CMAKE_FIND_LIBRARY_SUFFIXES in this manner:
set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
That did not work. Difficult for you to know that was what I did in any case,
sorry for not adding that info in the first mail. Removing the "", and then it
worked:
set(CMAKE_FIND_LIBRARY_SUFFIXES .a)
In FindBLAS.cmake I find the following:
if(BLA_STATIC)
set(CMAKE_FIND_LIBRARY_SUFFIXES ".a;.so")
endif(BLA_STATIC)
I believe the second line should be
set(CMAKE_FIND_LIBRARY_SUFFIXES .a .so)
instead? (same fix goes for APPLE/WIN32 part) Or is there some other difference
between lists and strings which I am unable to comprehend?
Cheers,
Yngve
