From 54aa9d51b09d67e90db443f682cface795f5af9e Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Sat, 6 Jul 2019 09:38:59 +0200 Subject: [PATCH] Fix default installation paths on mingw Mingw config targets assumed that resulting programs and libraries are installed in a Unix-like environment and the default installation prefix was therefore set to '/usr/local'. However, mingw programs are installed in a Windows environment, and the installation directories should therefore have Windows defaults, i.e. the same kind of defaults as the VC config targets. A difficulty is, however, that a "cross compiled" build can't figure out the system defaults from environment the same way it's done when building "natively", so we have to fall back to hard coded defaults in that case. Tests can still be performed when cross compiled on a non-Windows platform, since all tests only depend on the source and build directory, and otherwise relies on normal local paths.
