I'm trying to install ffmpeg (and some other libraries, but ffmpeg alone fails too) with conan to cross compile from linux (ubuntu) to windows.

Conan throws an error on Running configure, inside build(). It says that x86_64-w64-mingw32-gcc is unable to create an executable file..

On the config log I discovered it's because of a flag when running tests for x86_64-w64-mingw32-ld.

I've tried to get conan to not add the -m64 flag, but I haven't been able to get it working. Setting env variables like LDFLAGS= doesn't seam to work either on the conan profile, on the conanfile.py or directly on my terminal. Any suggestions?
