Hi Alan,
Thanks a lot! Yeah I was thinking about something along those lines, but i
was wondering if there is a solution that does not involve modifying the
submodules.

Hi Tiago:<br>
<br>
You could brute force it by surrounding each install directive in<br>
submodule by<br>
<br>
if(INSTALL_SUBMODULE)<br>
....<br>
endif(INSTALL_SUBMODULE)<br>
<br>
Then add<br>
<br>
option(INSTALL_SUBMODULE, "Install submodule?" OFF)<br>
<br>
to your top-level CMakeLists.txt file.<br>
<br>
Then because of that OFF, by default users would not install<br>
submodule, but if users desired that install, they could specify the<br>
-DINSTALL_SUBMODULE=ON option on the cmake command line. Or you could<br>
choose to default to ON.<br>
<br>
Note, I have characterized the above as brute force, but in fact the<br>
method is completely flexible, and most mature CMake projects use this<br>
kind of option-based method a lot.<br>
