I assume there is a problem with WHERE the generated file is located.
In the docs they say:
FLEX_TARGET(MyScanner lexer.l  ${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp)

so try to use ${CMAKE_CURRENT_BINARY_DIR}/src/test.c

The docs says:
FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])

I assume you can do:

FLEX_TARGET(Test ../src/test.l  ${CMAKE_CURRENT_BINARY_DIR}/src/test.c COMPILE_FLAGS "-L xxx -D xxx")
