How to point to a local installation of `corrade` without using the bootstrap project?

I would like to build magnum
with a local installation of corrade
(i.e. a local build installed in an arbitrary folder on my system).
I can specify -DCORRADE_INCLUDE_DIR="/c/whatever/corrade/build/install/include
, but CMake fails to find corrade-rc
, Utility
and other things. I tried specifying those manually, but FindCorrade
doesn't expose all the required variables.
I propose adding a CORRADE_ROOT
variable that can be pointed to "/c/whatever/corrade/build/install"
in my case, and CORRADE_INCLUDE_DIR
defaulted to ${CORRADE_ROOT}/include
if CORRADE_ROOT
is specified.
CMake has a <PackageName>_ROOT
builtin since 3.12, but I'd have to enable policy CMP0074 to make that work. (I thought I already enabled it but apparently not, heh -- will do.) Then you could use Corrade_ROOT
(not uppercase) and it'd "just work" without any other changes needed from my side.
Until then, putting the installation path to CMAKE_PREFIX_PATH
should work, separate with semicolons if you have more of them. So for example -DCMAKE_PREFIX_PATH="/c/whatever/corrade/build/install;/c/whatever/magnum/build/install"
, or install everything into a single location.
Thank you for the quick turnaround!
