<body><div style="font-family:Arial;">Hi Florent,<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">thank you so much. EXCLUDE_FROM_ALL does indeed have the effect of ignoring any install() invocations from within the subdirectory. I remember stumbling across this option, but from the docs I didn't get the impression that this would affect the installation as well.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">Maybe the documentation needs a few more words here.<br></div>
<div style="font-family:Arial;"><br></div>

</div>
<div>Also, 3rdparty libraries should be tagged like that anyway to be built only when they are used by the main targets. <br></div>
</div>
</blockquote><div style="font-family:Arial;">Yes, this is a good idea.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">Thanks again,<br></div>

<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> we are using the CMake install mechanism "install(...)" to copy all<br></div>
<div style="font-family:Arial;"> relevant files and target binaries of the product into the CMake install<br></div>
<div style="font-family:Arial;"> prefix folder, for further packaging. So far so good.<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> We are also using several thirdparty libraries, hosting them inside our<br></div>
<div style="font-family:Arial;"> own repository and building them along with our own code, usually using<br></div>
<div style="font-family:Arial;"> add_subdirectory utilizing their native CMake buildsystem.<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> Turns out, other developers also like the CMake install mechanism.<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> So now the INSTALL target of our whole project also installs thirdparty<br></div>
<div style="font-family:Arial;"> components, which we do not want to deliver with our own product (think<br></div>
<div style="font-family:Arial;"> static libraries, which are already linked into our executable).<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> After a lot of googling, here's my question: Is there a clean way to<br></div>
<div style="font-family:Arial;"> disable the install target for a subdirectory _without_ also disabling<br></div>
<div style="font-family:Arial;"> it completely for the remaining project?<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> What we already tried:<br></div>
<div style="font-family:Arial;"> * Setting CMAKE_INSTALL_PREFIX to a temporary directory for the<br></div>
<div style="font-family:Arial;"> subdirectory (doesn't work)<br></div>
<div style="font-family:Arial;"> * "function(install) endfunction()" to disable the install function for<br></div>
<div style="font-family:Arial;"> the subdirectory (breaks CMake in hilarious ways)<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> What we now do:<br></div>
<div style="font-family:Arial;"> Using a custom target, we patch the cmake_install.cmake files in the<br></div>
<div style="font-family:Arial;"> build directories before installing (works, but it's an abomination of<br></div>
<div style="font-family:Arial;"> a hack)<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> Any help? I think it's a valid usecase for CMake but there doesn't seem<br></div>
<div style="font-family:Arial;"> to be an easy way to do it.<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> We are using CMake 3.5.<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> Thank you :)<br></div>
