I built Glew using MinGW and the Kicad build is still failing to link 
pcbnew, but the error messages are different.

[100%] Building CXX object 
pcbnew/CMakeFiles/pcbnew.dir/__/common/base_units.cpp

Here are the commands I used to build Glew

gcc -DGLEW_NO_GLU -O2 -Wall -W -Iinclude -DGLEW_BUILD -o src/glew.o -c 
src/glew.c

gcc -shared -Wl,-soname,libglew32.dll 
-Wl,--out-implib,lib/libglew32.dll.a -o lib/glew32.dll src/glew.o 
-L/mingw/lib -lglu32 -lopengl32 -lgdi32 -luser32 -lkernel32

ar cr lib/libglew32.a src/glew.o

In Cmake, I have

GLEW_GLEW_LIBRARY =glew-1.10.0/lib/libglew32.a

Any tips to help me figure out what I'm doing wrong?

David
