Cmake Set Option Before Add Subdirectory

Before the add subdirectory command or.

Cmake set option before add subdirectory. Cmake s option command more or less adds a boolean variable to the cache. The cmakelists txt file in the specified source directory will be processed immediately by cmake before processing in the current input file continues beyond this command. Lots of people use gtest surely someone has run into this before. If the exclude from all argument is provided then targets in the subdirectory will not be included in the all target of the parent directory by default and will be excluded from ide project files.

I tried to set the options on top level cmakelists txt but nothing change. Jww nov 18 18 at 1 12 ronkot like in your linked answer i would add that sometimes it is necessary to add force as additional parameter after the description string. So now what. How does one set an option declared by a subdirectory before entering that subdirectory.

I m not sure how much this is meant to be supported. Something like project name strequal cmake project name to set the default for the package tests option since this should only build by default if this is the current project. Users will have to explicitly start a build in the generated output directory. I thought it did but.

Hi gerry setting these variables by hand sounds quite dangerous. Ldd reports what the run time linker can find. I m using the cmake version 3 15 5. Add subdirectory source dir binary dir where source dir would be the source directory relative to cmake source dir and binary dir could be any absolute path of your choice.

Sorry what i stated before does not work either. The documentation for add subdirectory suggests states the following. Which is why we have to define the option ourselves before google test does. Any pointer about what i m doing wrong is really welcome.

Cmake not creating the dynamic links. Cmake will always use the values it finds there before anything set in a set or option command. I have one set of options that i invoke cmake with for llvm but one subproject seems to need an extra option. If you want to override the default value of an option simply add a variable of the same name to the cache yourself before pulling in the subproject.

While this boolean option is stored in the cache and accessible as a variable you cannot override the initialvalue by setting a variable of the same name beforehand not even by passing a d command line option to cmake. As mentioned before you have to do the enable testing in your main cmakelists. I m starting to suspect that everyone who needs this to work unattended edits the gtest source to change the default there. Now in your tests directory.
