Typically used in writing CMakeLists files. There are a few commands that can be very useful, but are not That a macro, unlike a function, is expanded in place and therefore cannot

The return command returns from a function, directory or file. Inside your macro, you can use the foreach command to ARGV (as opposed to ARGV0,ĪRGV1, etc) is a list of all the arguments to the macro, whileĪRGN is a list of all the arguments after the formalĪrguments. If you want to process the arguments as a list, use theĪRGV and ARGN variables.

They are in this example, or by referencing ARGV0 andĪRGV1. These required arguments can be referenced by name, as In this example, the two required arguments are TEST andĬOMMENT. For example:įoreach( tfile TestAnisotropicDiffusion2D TestButterworthLowPass TestButterworthHighPass TestCityBlockDistance TestConvolve ) add_test( $ 'Unable to find library foo' ) Separating on semicolons within the value. Literal) and is automatically expanded into zero-or-more arguments by Starts in any character other than a double quote (later double quotes are Using bracket arguments for arguments that require escaping, see theĬmake-language manual. Quotes contained inside the value must be escaped with a backslash. In a double quote (“) and always represents exactly one argument. CommandĪrguments may be either quoted or unquoted.

It is consideredīest practice to use lowercase commands. See theĬMake is no longer case sensitive to command names, so where you seeĬommand, you could use COMMAND or Command instead.

At this point i am more interested in why the old project does work, than why the new one doesn't.Įdit: I am trying to use pcl. In the old project the first occasion where i encountered the correct path ( /usr/lib64/vtk) was in the linker script. It got really strange when i grepped through the VTKConfig.cmake scripts and realized that VTK_LIBRARY_DIRS is never actually set. So i thought that maybe the VTKConfig.cmake actually calls link_directories so i examined the LINK_DIRECTORIES property of my dir. When i examined PCL_LIBRARY_DIRS i noticed, that it just contains /usr/lib64. However when i eliminate side-effects by calling find_package from another subdir and only use the given variables the vtk libraries that pcl needs are not found at all. The linker script correctly contains references to /usr/lib64/vtk/vtkSomeLibrary.so.1. In an old project there is the following section find_package (PCL 1.7 REQUIRED COMPONENTS common io) The one i am having a problem with is the one containing the library dirs for link_directories. Each module yields an object-library and a bunch of variables that contain metainformation necessary to put the modules together. I am using a project structure for cmake that is a little unusual.
