<div>Q: What is the appropriate way of doing this?<br>A: Not sure about "appropriate", but here's one way that I achieve that goal... :-)<br><br>SET(MY_OWN_INSTALL_PREFIX "/usr/thispkg" CACHE PATH "Prefix prepended to install directories")
<br></div><span class="sg"><div>SET(CMAKE_INSTALL_PREFIX "${MY_OWN_INSTALL_PREFIX}" CACHE INTERNAL "Prefix prepended to install directories" FORCE)<br>
<span class="sg"><div><br>That way, you have a cache variable that CMake knows nothing about (and hence, has no default value for it) that you are in charge of priming, but that the user can still change through the ccmake/CMakeSetup guis... that always gets propagated into CMAKE_INSTALL_PREFIX because of the FORCE. (And gets hidden from the guis because of the INTERNAL.)
<br><br>Of course, the FORCE means you cannot override via -DCMAKE_INSTALL_PREFIX, but you could still override via -DMY_OWN_INSTALL_PREFIX.<br></div></span></div></span><br><br>HTH,<br>David<br><br><br><div><span class="gmail_quote">

<div style="">Is there a way to override CMAKE_INSTALL_PREFIX in a multi-level CMake project? Since my package has a long history of being installed in a location other than /usr/local, I really want to have the default match previous practice.
