From 0278989405eea53ca7e5f1bfa6af9aea7a0b49c5 Mon Sep 17 00:00:00 2001 From: Brad King Date: Fri, 5 Aug 2016 15:55:32 -0400 Subject: Ninja: Add `$subdir/{test,install,package}` targets With the Makefile generator one can use `cd $subdir; make install` to build and install targets associated with a given subdirectory. This is not possible to do with the Ninja generator since there is only one `build.ninja` file at the top of the build tree. However, we can approximate it by allowing one to run `ninja $subdir/install` at the top of the tree to build the targets in the corresponding subdirectory and install them. This also makes sense for `test`, `package`, and other GLOBAL_TARGET targets. It was already done for `all` by commit v3.6.0-rc1~240^2~2 (Ninja: Add `$subdir/all` targets, 2016-03-11). --- Help/generator/Ninja.rst | 17 ++++++++++++++--- Help/release/dev/ninja-directory-targets.rst | 8 ++++++++ Source/cmGlobalNinjaGenerator.cxx | 11 ++++++++--- Source/cmNinjaTargetGenerator.cxx | 13 +------------ Source/cmNinjaUtilityTargetGenerator.cxx | 17 ++++++++++++----- Tests/RunCMake/Ninja/RunCMakeTest.cmake | 6 ++++++ Tests/RunCMake/Ninja/SubDir-install-stdout.txt | 1 + Tests/RunCMake/Ninja/SubDir-test-stdout.txt | 1 + Tests/RunCMake/Ninja/SubDir.cmake | 5 +++++ Tests/RunCMake/Ninja/SubDir/CMakeLists.txt | 4 ++++ 10 files changed, 60 insertions(+), 23 deletions(-) create mode 100644 Help/release/dev/ninja-directory-targets.rst create mode 100644 Tests/RunCMake/Ninja/SubDir-install-stdout.txt create mode 100644 Tests/RunCMake/Ninja/SubDir-test-stdout.txt diff --git a/Help/generator/Ninja.rst b/Help/generator/Ninja.rst index d94e5f6..ef0e28b 100644 --- a/Help/generator/Ninja.rst +++ b/Help/generator/Ninja.rst @@ -7,6 +7,17 @@ A build.ninja file is generated into the build tree.
