I’m trying to install a package called libsnark on a mac (OS 15.1.1, M3). I’m using cmake 3.31 available from homebrew. Its CMakeLists.txt file starts with
cmake_minimum_required(VERSION 2.8)
project (libsnark)
Nevertheless, when I run cmake I get the following errors/warnings:
CMake Warning (dev) in CMakeLists.txt:
cmake_minimum_required() should be called prior to this top-level project()
call. Please see the cmake-commands(7) manual for usage documentation of
both commands.
and
CMake Warning (dev) in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as
project(ProjectName)
near the top of the file, but after cmake_minimum_required().
CMake is pretending there is a "project(Project)" command on the first
line.
Why is this happening, and how can I debug this?
Right after the above lines there is the following
set(
CURVE
"BN128"
CACHE
STRING
"Default curve: one of ALT_BN128, BN128, EDWARDS, MNT4, MNT6"
)
Nevertheless, later in the file it has
if(${CURVE} STREQUAL "BN128")
add_definitions(
-DBN_SUPPORT_SNARK=1
)
endif()
but this gives the error
CMake Error at CMakeLists.txt:2 (if):
if given arguments:
"STREQUAL" "BN128"
Unknown arguments specified
(It’s strange that this says it’s at line 2, when the actual statement is at line 165).
An suggestions as to how to debug this?
