Dear all,
I know this is a frequent question on this mailing list, but I'm being
a bit overwhelmed with information and not too sure which direction I
should head.
Basically, I have executables X and Y who are each top-level projects.
They make use of library A. Library A in turn makes use of library B.
Both A and B are libraries which are linked to, but they are also
executables -- I compile with a temporary main () function in order to
do some tests. That is, their CMakeLists.txt generate both a library
and an executable.
So, the dependencies are like this:
X <-- A <-- B
Y <-- A <-- B
What I'm confused about are:
1) Should all 4 have their own Project () lines?
2) Should X and Y have ExternalProject () lines to A?
3) Should A have ExternalProject () lines to B?
4) Or maybe instead of ExternalProject (), I should use Add_Subdirectory ()?
5) Or should X and Y have Target_Include_Directories () to A; should
A have a Target_Include_Directories () to B?
...or maybe something else?
What I think is that they should all have their own Project (). And
perhaps A and B should have Install () lines that install libraries
into ${CMAKE_INSTALL_PREFIX}/lib/ and header files to
${CMAKE_INSTALL_PREFIX}/include/. Then, X, Y, and A needs
Target_Include_Directories () to this path and *NOT* the where the
source code of A and B reside.
All this removes ExternalProject () from the picture... It's true
what I'm including is mine but these libraries could be used
separately by other programs (i.e., Y).
I hope this is clear -- there are just too many options and the
documentation is thorough but the difference between each seems small.
At least too small for me to distinguish...
Thank you!
Ray
