Let's keep jasper disabled for now, as it produces build errors:
/mnt/Lavoro/mxe/mxe/usr/x86_64-w64-mingw32.shared/include/jasper/jas_math.h:
In function 'bool jas_safe_intfast32_mul(int_fast32_t, int_fast32_t,
int_fast32_t*)':
/mnt/Lavoro/mxe/mxe/usr/x86_64-w64-mingw32.shared/include/jasper/jas_math.h:241:12:
error: 'INT_FAST32_MAX' was not declared in this scope
if (x > INT_FAST32_MAX / y) {
^
It's not a required dependency, but we might want to add it later if
someone asks for it (and can provide a solution).
