Modifying Cmake to have Deal.ii include paths

[Xavier Johnson]

Hi,

This may be a newb question. I am probably struggling understanding how to set paths in cmake and spent some time reading the documentation for cmake.

My question is, how can I set the DEAL_II_DIR in the CMakeLists.txt so I don't have to provide a path every time I call the cmake command?

Thanks

Hi Xavier,

i think the following command will do:

set(DEAL_II_MIN_VERSION "9.5.0")
set(DEAL_II_DIR "~/.local/lib/dealii")
find_package(deal.II ${DEAL_II_MIN_VERSION} REQUIRED
HINTS ${DEAL_II_DIR} ../ ../../ $ENV{DEAL_II_DIR})
IF(NOT ${deal.II_FOUND})
MESSAGE(FATAL_ERROR
"*** Could not locate a (sufficiently recent) version of deal.II. ***\n"
"You may want to either pass a flag -DDEAL_II_DIR=/path/to/deal.II to cmake"
" or set an environment variable \"DEAL_II_DIR\".")
ENDIF()

Regards,
Nils

Hello,

You can just set DEAL_II_DIR in your environment. If you are using bash you can do `export DEAL_II_DIR=/path/to/deal.II` in your terminal or put that line you .bashrc if you want to do this permanently. Personally, I just write the cmake line in a file and make the file executable. When I need to call cmake, I just call the executable.

Best,

Bruno
