I'd like to add a variable that the user must set after clicking "Configure" in cmake-gui. Is there a way to do this?

Options and variables are defined on the CMake command line like this: $ cmake -DVARIABLE=value path/to/source You can set a variable after the initial `CMake` invocation to change its value. You can also undefine a variable: $ cmake -UVARIABLE path/to/source Variables are stored in the `CMake` cache.
CMAKE_CONFIGURATION_TYPES. Specifies the available build types (configurations) on multi-config generators (e.g. Visual Studio, Xcode , or Ninja Multi-Config ). Typical values include Debug , Release , RelWithDebInfo and MinSizeRel , but custom build types can also be defined.
There are two different ways to configure with cmake ; one is to run cmake in a fresh directory passing some options on the command line, and the other is to run ccmake and use its editor to change options. For both, assume you are in a directory called debug and the IMP source is in a directory at ../imp .
cmake the corresponding version file is located next to it and named either <config-file>-version. cmake or <config-file>Version. cmake . If no such version file is available then the configuration file is assumed to not be compatible with any requested version.
Using the set command, specify CACHE parameters, e.g.
set(NAME_INCLUDE "default value" CACHE FILEPATH "description") set(NAME_LIB "default value" CACHE FILEPATH "description") In the GUI CMake will group all variables with the same prefix.
See the CMake documentation for set.
