+Subject: [PATCH] Fix #5410: fix installing libgit2.pc in wrong location
+
+Remove using custom PKG_BUILD_PREFIu, PKG_BUILD_LIBDIR and
+PKG_BUILD_INCLUDEDIR variables.
+Use cmake CMAKE_INSTALL_PREFIX, LIB_INSTALL_DIR, INCLUDE_INSTALL_DIR instead.
+This patch fixes install libgit2.pc file in correct location and simpifies
+cmake module.
