From 1ddcc582c1a408e054efdcc32c00a8c07299d115 Mon Sep 17 00:00:00 2001 From: "Daniele E. Domenichelli" Date: Fri, 6 Dec 2013 17:09:27 +0100 Subject: ExternalProject: Add EXCLUDE_FROM_ALL option to ExternalProject_Add When adding a new external project, the "all" target will depend on this. This option allows one to add an external project will not be executed when the "all" target is executed. The reason for this is that an external project could be useful, for example, only for running tests, and therefore not necessary during the build. --- Modules/ExternalProject.cmake | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/Modules/ExternalProject.cmake b/Modules/ExternalProject.cmake index 3c86331..0f651e9 100644 --- a/Modules/ExternalProject.cmake +++ b/Modules/ExternalProject.cmake @@ -16,6 +16,7 @@ # [LIST_SEPARATOR sep] # Sep to be replaced by ; in cmd lines # [TMP_DIR dir] # Directory to store temporary files # [STAMP_DIR dir] # Directory to store step timestamps +# [EXCLUDE_FROM_ALL 1] # The "all" target does not depend on this # #--Download step-------------- # [DOWNLOAD_NAME fname] # File name to store (if not end of URL) # [DOWNLOAD_DIR dir] # Directory to store downloaded files @@ -1913,6 +1914,9 @@ function(ExternalProject_Add name) set(cmf_dir ${CMAKE_CURRENT_BINARY_DIR}/CMakeFiles) set(complete_stamp_file "${cmf_dir}${cfgdir}/${name}-complete") + # The "ALL" option to add_custom_target just tells it to not set the + # EXCLUDE_FROM_ALL target property.
