hello<br>
<br>
I assign the list of all directories the names of which starts with a<br>
pattern like pattern_.... to a cmake variable which I then pass as a<br>
preprocessor macro:<br>
<br>
FILE(GLOB MYPROJECT_LIST_SYSTEMS RELATIVE ${CMAKE_SOURCE_DIR} system_*)<br>
<br>
MYPROJECT_LIST_SYSTEMS is then a cmake "list", a string with semicolon<br>
separators.<br>
<br>
What is the maximum number of entries in the list that cmake handles?<br>
Or what is the maximum length of a cmake string?<br></blockquote><div><br></div><div>In theory, it should be around 2G for 32-bit build of CMake.</div><div><br></div><div>In practice, I bet you'll run into the beginnings of performance issues if you start to have strings that are 10s or 100s of megabytes large.</div>
