[vlc-devel] [3.0 PATCH v2 15/20] contribs: glew: Simplify/improve the win32 patch, fix building with lld

[Steve Lhomme]

From: Martin Storsjö <martin at martin.st>

The previous version of win32.patch left things in a bit more broken state
than necessary.

The previous version of the patch removed LD=gcc and removed a number of
flags, making the build trying to build a DLL (but without the option
-shared), actually producing an EXE. (The linked DLLs are later
actually removed by the contribs build system.) Instead of removing LD=gcc,
change it into LD=$(CC) which is more what glew originally intended, and
keep the flags for linking shared libraries (but remove the -soname option
which isn't supported by neither GNU ld nor lld).

This fixes building in setups where $(LD) points to lld.

(cherry picked from commit 41b5dca1f870aa1fbc32703daf875c35aa979fd9)
