[Insight-developers] Finding include and lib directories

[Luis Ibanez]

Hi Paul,

It seems it is not necesary to modify all the
CMakeList.txt files to make them work for Linux.


You only need to define the environment variables:

THREADS_LIBS  as   -lpthread

and


DL_LIBS    as     -ldl


CMake recursively access the CMakeList.txt files in the
parent directories.

The one at the root (Insight) already contains the lines:

UNIX_LIBRARIES(
${THREAD_LIBS}
${DL_LIBS}
-lm
}


The includes directories are also set in this unique file under:

INCLUDE_DIRECTORIES(
...
)

---

Using directly the names of the libraries in each CMakeList.txt
will not work well because libraries like -ldl doesn't exist on Windows.

(Right now the CMakeList.txt files doesn't work on Windows)

---

It could be useful to add in the InsightStart.doc the list of
environment variables that should be set on Unix before
running  configure.... including a  mention  to setenv   CC=gcc      :-)


Thanks,



Luis
