VS macros not expanded in Import nodes

[nitrocaster]

I'm trying to use this tool on my project. Here's a piece of log that I get:

pi@nitrocaster-pi:~/git/eagleview/src $ cmake-converter -s eagleview.sln
0.000383 processes count = 4
0.000592 warnings level = 2

(...)

From the log it seems that cmakeconverter doesn't expand $(SolutionDir) when parsing the following node in vcxproj file:
<Import Project="$(SolutionDir)Common.props" />

In ../externals/CMakeLists.txt I found this line, which indeed contains unexpanded SolutionDir macro:
use_props(${PROJECT_NAME} "${CMAKE_CONFIGURATION_TYPES}" "$(SolutionDir)Common.cmake")
