cmake error libcurl not found, but libcurl4 is installed – Debian

I am trying to compile the Springlobby version 268 client from the open source game TA-Spring. However the newest version (271) compiles just fine. But when I try to compile version 268 I get the CMake-error:

CMake Error at /usr/share/cmake-3.18/Modules/FindCURL.cmake:163 (message):
  CURL: Required feature libcurl is not found
Call Stack (most recent call first):
  src/CMakeLists.txt:127 (FIND_PACKAGE)

I am compiling on Debian testing and tried the libraries libcurl4-openssl-dev, libcurl-gnutls-dev and libcurl4-nss-dev all without success.

game: https://springrts.com
lobby 0.271: https://github.com/springlobby/springlobby
lobby 0.268: https://github.com/springlobby/springlobby/tree/0.268
install from source: https://github.com/springlobby/springlobby/wiki/Installfromsource

Building the lobby from git repo:

git clone --recursive https://github.com/springlobby/springlobby.git
cd springlobby
cmake .
make
make install

The Springlobby version 271 uses libcurl4-openssl-dev but version 268 seemingly links to an older libcurl.

    The Springlobby 0.268 supports the older lobby servers with most players on it as well as the newer ones.
    So in case you want to compile and use the older 0.268 Springlobby, you have to git clone the current version like I already wrote and then cherry pick the older version by:

    git checkout 0.268

    Apply the posted fix by Tsyvarev in src/CMakeLists.txt, line 127. But you also have to add:

    #include <string>

    to the files src/battlelist.h and src/utils/sortutil.h below the includes at the top of these files.

    Version 268 incorrectly calls find_package (src/CMakeLists.txt:127):

    FIND_PACKAGE( CURL REQUIRED libcurl )

    The last parameter libcurl is interpreted (according to find_package documentation) as the element of COMPONENTS list, and in case of FindCURL.cmake it is treated as PROTOCOL/FEATURE specification. Obviously, libcurl means neither protocol nor feature.

    Commit https://github.com/springlobby/springlobby/commit/252c4cb156c1442ed9b4faec3f26265bc7c295ff fixes this call to

    FIND_PACKAGE(CURL REQUIRED)
