From af8c491904e084ad153cbeee82110c29f91a5fa3 Mon Sep 17 00:00:00 2001 From: Harald Sitter Date: Mon, 18 Mar 2019 15:37:52 +0100 Subject: find ruby gems & make coverage conditional on BUILD_COVERAGE Summary: new finding tech: - find_gem function configures gem-specific FindFoo files and wraps around find_package - FindFoo files look for ruby and then attempt to require the gem name i.e. it checks if the gem can be successfully loaded by the interpreter - since this is based on find_package it may be influenced in all the regular ways (e.g. forced found or disabled from finding altogether via CMAKE_DISABLE_FIND_PACKAGE_$PKGNAME) various notes for the future: - technically this isn't 100% correct because the require name of a gem and the gem name may not be the same. e.g. the gem `docker-api` has the require name `docker`. for all currently used gems the names are however the same and so simply requiring the gem name is expected to work - the implementation doesn't care about versions, again because we don't need it to - test-unit is a bundled gem, some distributions (e.g. Arch) do split it out without making suitable dependency arrangements on a package level though the tech is heavily inspired by Aleix Pol's tech for finding QML modules as seen in extra-cmake-modules Test Plan: - ruby not found: none of the modules found - test-unit not present: error - simplecov not prseent: never errors - having a module installed or not is reported in the cmake output Reviewers: #dolphin, elvisangelaccio Reviewed By: #dolphin, elvisangelaccio Subscribers: elvisangelaccio, kfm-devel Tags: #dolphin Differential Revision: https://phabricator.kde.org/D19856 --- cmake/FindGem.cmake | 39 +++++++++++++++++++++++++++++++++++++ cmake/FindGem.cmake.in | 53 ++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 92 insertions(+) create mode 100644 cmake/FindGem.cmake create mode 100644 cmake/FindGem.cmake.in (limited to 'cmake') diff --git a/cmake/FindGem.cmake b/cmake/FindGem.cmake new file mode 100644 index 000000000..11c9c672b --- /dev/null +++ b/cmake/FindGem.cmake @@ -0,0 +1,39 @@ +#============================================================================= +# Copyright (c) 2019 Harald Sitter +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# +# 1.
