Re: [CMake] Adding definitions to compile one file ?

HI Petr

Thanks for the suggestion.
But this will erase the existing compile definitions, won't it ?
So may be I should do a get_property first,
append my new definitions and reset the property ?
I'll try anyway...

Hi Vania.

For your case, it's best to forget about thenot-as-convenient-as-they-could-be convenience functionsset_*_properties, and just invoke set_property:


set_property(
  SOURCE source.cpp
  PROPERTY COMPILE_DEFINITIONS
    VAR1=${MY_VAR1} VAR2=${MY_VAR2}
)

    Hi

    I want to add two definitions to compile one specific files
    in addition to the global definitions.
    I have the following problem. If I use

    set_source_files_properties(source.cpp
    PROPERTIES
    COMPILE_DEFINITIONS VAR1=${MY_VAR1} VAR2=${MY_VAR2} )

    then I get error message incorrect number of arguments for
    set_source_files_properties

    If I put
    set_source_files_properties(source.cpp
    PROPERTIES COMPILE_DEFINITIONS "VAR1=${MY_VAR1} VAR2=${MY_VAR2}" )

    then it generates strangely enough the compile command

    /usr/bin/c++ -DVAR1="path1 VAR2=path2" ... source.cpp

    with the double quotes as above, which gives a weird value to VAR1
    and no value to VAR2

    If I use twice set_source_files_properties
    the first one is overwritten by the second
    and I only get the definition of VAR2

    What am I supposed to do ?

    Thankx

    PS I am using cmake 3.2.2 on Linux Mint.
