NuGet with TeamCity for project shared by 2 solutions - .h file not found

Question

The environment before NuGet (simplified):

• One project shared by 2 solutions (sol1 and sol2).
• both solutions are successfully build by TeamCity.

Adding NuGet

• In sol1 I added a package to the project (Casablanca's C++ REST API).
• In one of the .c file in the project I added #include <cpprest/json.h>.
• In both solutions if have enabled NuGet package restoration.

Result

• Locally both solutions are still successfully build.
• Sol1 is build successfully on the TeamCity as well.
• Sol2 failed to build on the TeamCity given an error that the cpprest/json.h file can't be found when trying to compile the .c file.
• Note: during the build of sol2 on the TeamCity I see that the package is successfully downloaded and installed.

What can cause Sol2 to be unable to find the included json.h file?

Answer 1

#include <cpprest/json.h>

probably has to be something like

<../packages/casablancaapi/native/lib/cpprest/json.h>
