Hi everyone, I would like to create a CMake test that does the following: * Download a file from an external resource * Do something with the file * compile an executable myTest * execute myTest outputfile
Using ExternalData for downloading the file works well, but the second step (file conversion, in this example cp for simplicity) does not work: ``` cmake_minimum_required(VERSION 3.2) project(mytest) # Download the files INCLUDE(ExternalData) set( ExternalData_URL_TEMPLATES "https://downloads.sourceforge.net/project/noshdata/%(algo)/%(hash)" ) ExternalData_Expand_Arguments( testFetchData OUT_DATA DATA{${CMAKE_SOURCE_DIR}/test.e} ) ExternalData_Add_Target(testFetchData) add_custom_command( OUTPUT test.g COMMAND cp test.e test.g DEPENDS test.e ) ADD_EXECUTABLE("myTest" main.cpp) add_test(myTest test.g) ``` I suppose I'm missing something about the dependencies here; after all, the `add_custom_command` has to wait for `testFetchData` to complete. Likewise, `add_test` has to wait for `add_custom_command` to complete. Hints appreciated. Cheers, Nico
