CMake builds empty .lib and .dll?

[gedOHub]

Hello,
After build with cmake .dll file is empty. My CMake outputs:

With DLL Export Viewer I see this is empty
When I try to load .lib file I get:

Error 17 error LNK2001: unresolved external symbol

Founded my problem- mistake in PATH variable. Buillded with nmake.

[weinrank]

Thx for the Feedback, does the correct PATH variable also fix the issue with a CMAKE built?

[gedOHub]

Can't say right now. .dll file is same- empty, but lib file size is bigger then earlier. Haven't tested

[weinrank]

Okay, i see the issue: We don't generate export headers.

We'll try to fix this soon.
