CMake Error: "Could not find QCA"

Question

I'm trying to run CMake on the latest clone of QGIS, but I'm getting this error:

Found SpatiaLite: C:/OSGeo4W/lib/spatialite_i.lib

...
CMake Error at cmake/FindQCA.cmake:58 (message):
  Could not find QCA
Call Stack (most recent call first):

Did I set up the build process incorrectly? I'd appreciate any and all help, thanks!

Answer 1

You need to install libqca2-dev.

sudo apt-get install libqca2-dev

I also had to change the WITH_QWTPOLAR flag to OFF (on the ccmake gui) to be able to compile the sources.

These were the only things I've changed to compile QGIS. I've followed the available documentation to build QGIS.
