From 9fa7f2b113927ee0c53f137948deb2dadfa3cc4d Mon Sep 17 00:00:00 2001 From: Samuel Martin Date: Wed, 22 Jan 2014 21:59:37 +0100 Subject: [PATCH] pkg-cmake.mk: build shared library when !BR2_PREFER_STATIC_LIB CMake offers a couple of places where one can specify how to build a library: - when you create the library target itself, by calling add_library(target [SHARED|STATIC] ...) - or globally, when you configure the build, by setting the BUILD_SHARED_LIBS CMake flag. * if the library target kind of library is specified: it overrides the global setting BUILD_SHARED_LIBS; * else, if the global setting BUILD_SHARED_LIBS is set: it builds according to the BUILD_SHARED_LIBS flags; * otherwise: for linux, it will build static library (like BUILD_SHARED_LIBS default is OFF). So, we can consider the setting BUILD_SHARED_LIBS acts a bit similarly to the autotools ones '--disable-static' and '--enable-shared'. Thus, it makes sense for Buildroot to globally drive to CMake flags in the cmake-package infrastructure. It seems we never trigger this so far because: - either we specified it in the *.mk file (e.g. opencv.mk); - or it was already set per target by the projects' upstreams. Followup patches will clean the remaining BUILD_SHARED_LIBS in the package *.mk files.
