Build multiple CMake configurations

Hi,

I am using AppVeyor to build a C++ library that uses CMake as build system. The library can be built as both static and dynamic library and this can be configured by passing either -DBUILD_SHARED_LIBS=0 or -DBUILD_SHARED_LIBS=1 as command line argument to cmake. How can I configure AppVeyor (using appveyor.yml) so that it builds both versions? The current appveyor.yml looks like this:

version: 1.0.{build}
image:
- Visual Studio 2019
- Visual Studio 2017
configuration:
- Debug
- Release
before_build:
- cmd: cmake -H. -B./build -DBUILD_SHARED_LIBS=1
build:
  verbosity: normal

I tried wrapping the before_build in a for, but this did not work (AppVeyor ran once with -DBUILD_SHARED_LIBS=1 but skipped the ...=0 version):

for:
  -
    before_build:
    - cmd: cmake -H. -B./build -DBUILD_SHARED_LIBS=1
  -
    before_build:
    - cmd: cmake -H. -B./build -DBUILD_SHARED_LIBS=0

I also tried adding a matrix to the before_build, but this did not work either (AppVeyor showed Error parsing appveyor.yml: Script contents must be a string (Line: 10, Column: 3)):

before_build:
  matrix:
  - cmd: cmake -H. -B./build -DBUILD_SHARED_LIBS=1
  - cmd: cmake -H. -B./build -DBUILD_SHARED_LIBS=0

How can I configure AppVeyor so that it builds both versions?

Regards,
Philip

   Hi Philip,

   This is probably the config you are looking for:

   
   version: 1.0.{build}
   
   image:
   - Visual Studio 2019
   - Visual Studio 2017
   
   configuration:
   - Debug
   - Release
   
   environment:
     matrix:
     - DBUILD_SHARED_LIBS: 0
     - DBUILD_SHARED_LIBS: 1
   
   before_build:
   - cmd: cmake -H. -B./build -DBUILD_SHARED_LIBS=%DBUILD_SHARED_LIBS%
   
   build:
     verbosity: normal

   That works great, thank you! I did not know that you can use environment variables for this.
