A related question: if I include an external project in my solution
using
include_external_msproject(Bar ../../Bar/Bar.vcproj)
can I later refer to this project using

More generally, what is the correct way to specify that a CMake
target should be linked with some external library?
It is this last question I would like to get an answer to.
Say you have another project that produces a library called
libBar.dll and that library is located in C:\Libs then you can refer
to that library in CMake directly. In other words, the cmake code you
have is absolutely correct:
Target_link_Libraries(Foo Bar)
with the following caveat: libBar.dll MUST be in a known directory
that the linker will look in. You can make sure of this by adding the
following cmake code above the "target_link_libraries" code:
LINK_DIRECTORIES ("C:\Libs")
Ah. So if libBar.dll and libBar.lib are in different directories,
*both* directories must be added using LINK_DIRECTORIES(), right?
That should be documented somewhere (if it is, I've managed to miss it).
After testing this, it appears that I still get the same relinking
behavior.
Well, that turned out to be a little hasty conclusion.
In case of linking with a DLL, having paths to both the dll and import
lib in LINK_DIRECTORIES avoids relinking. So far, so good.
However, I still get relinks due to a dependency on a static library. In
this case, I'm unable to add the path using LINK_DIRECTORIES since the
path is different depending on the configuration. I'm currently adding
the path using the LINK_FLAGS_{DEBUG, ...} target property (which
probably is the cause of the relinking).
So, I would like to be able to do something like, given the debug
version of MyStaticLib.lib is in lib/win32/debug:
LINK_DIRECTORIES_DEBUG(lib/win32/debug)
TARGET_LINK_LIBRARIES(Foo MyStaticLib)
To make things more difficult, I cannot do something like:
LINK_DIRECTORIES("lib/win32/$(ConfigurationName)")
because the configurations available for the static library
(MyStaticLib.lib) do not map cleanly on the values for $(ConfigurationName).
<frustration>
Argh! Why can't things every be simple?!
</frustration>
Any hints on how to solve this?
