This commit performs two main changes: * Alters the shaders to use only strictly conformant GLSL 2.0. * Alters the Windows UI to use ANGLE via GL ES 2.0 and EGL 1.4. This commit also drops official support for Windows XP, since ANGLE requires a non-XP toolset to build. It is still possible to build SolveSpace for Windows XP using: cmake -T v120_xp -DOPENGL=1

# Find the given library in the system locations, or build in-tree if not found.

# Arguments:
|
|
# PKG_NAME - name of the package as passed to find_package
|
|
# PKG_PATH - name of the source tree relative to extlib/
|

|
|
# The rest of the arguments are VARIABLE VALUE pairs. If the library is not found,
|
|
# every VARIABLE will be set to VALUE and find_package will be rerun with the REQUIRED flag.

# Regardless of where the library was found, only the specfied VARIABLEs that start with
|

# ${PKG_NAME} will be set in the parent scope.

# All warnings in the in-tree package are disabled.
